It is usually colour coded to match your silicone. The reason is as you rub it up the aggregate rolls on the base and when it is all dried there is a risk of the base coat colour showing through the scratches.
If you use paint then Rendit can supply and Parex do a colour wash. Jub revitacolor is good as well. These paints come very thick and need watering down a lot if it is to be a colour wash and not look painted. I have added 40% water to jub and it was still a bit like paint.
I take them off and refit but in my small print I state it is expected that all outside fittings (electrical, satellite dishes, ornamental etc) should be removed prior to work commencing but we will remove as long as the client accepts responsibility for loss or damage.
With ewi I list what...
We all have some problems in life, my probably only issue was going cold turkey on Setraline, massive headaches! So coming off Nicotine, alcohol, drug etc can be a challenge but t usually ends up on the positive side.
Good luck with it.
A Rossi says they all tear or sponge up crap. I developed a technique of applying flat and smooth as I could wet and dealt with getting it smooth when set. More labour intensive but better results.
For arm ache I got the lab to do scraping and grinding, save yer joints wear out someone else’s lol.
Every manufacturer does an equivalent like Webers is their Lac, K Rend HPX etc.
I found Maite the worst to use but I also stopped sponging, instead spat flat then next morning I use a rasp type trowel from pft North to get any lines out.
